ARTHUR TREVOR DAWSON AND GEORGE THOMAS BUCKHAM, OF WESTMINSTER,

LONDON, ENGLAND, ASSIGNORS TO VICKERS LIMITED, OF WESTMINSTER,

LONDON, ENGLAND.

To all whom it may concern:

Be it known that we, Sir ARTHUR TREVOR DAWSON, knight, and GEORGE THOMAS BUCK- HAM, both subjects of the King of Great Britain, residing at Vickers House, Broadway, Westminster, in the county of London, England, have invented certain .new and useful Improvements in or Relating to Gun- Mountings, of which the following is a specification.

This invention relates to gun-mountings and has particular reference to naval mountings of the kind proposed by us lll'WhlCll the side cheeks of the carriage, instead of being provided with the usual center pivot, are ex tended downward and made integral with or suitably connected to a rotary chamber for the accommodation of the gun layers.

According to this invention the elevating mechanism in addition to being actuated by the elevating number through the usual hand wheel or crank is also capable of being actuated by the same elevating number ,through pedals suitably connected to the elevating mechanism. .In this manner we avoidthe-nece'ssity for employing an aux-- iliary elevating number for effecting the clearly understoodand readily carried into movement of the gun and sight through the large angles necessary to counteract the effect of the ships movements on the laying of the gun, the single elevating number performing this movement by means of the aforesaid pedals. Similarly the training mechanism may be under the control of a hand wheel or crank and pedals, both of 'which are operated by a single training number, the pedals being employed for moving the mounting when lar e variations in training are to be efiected. y avoiding the necessity for employing an auxiliary elevating or training .number, additional sighting gear with a consequent larger sight opening in the shield (when the latter is fitted) is dis ensed with.

11 order that the said invention may be effect wefwill describe the same more fully with reference to the accompanying drawin in which:-

igures 1 and 2 are respectivelya sectional side elevation and a sectional plan showing, in a more or less diagrammatic manner, a gun mounting provided with ele- Specification of Letters Patent.

yating and training mechanism constructed in accordance with our invention.

Fig. 3 is a side elevation on a larger scale showing a constructional form of the improved elevating or training mechanism, and

Fig. 4 is a section taken approximately on the line 11 of Fig. 3.

The gun mounting shown by Figs. 1 and 2 is similar to that already proposed by us, comprising a chamber A which is rotatably mounted in the deck in the case of a naval mounting, and is integral with or connected to the side cheeks A, A between which the elevating and training numbers are disposed. The chamber A carries two seats a, a one for the elevating and the other for the training number. Arranged in a convenient position relativelyto the seats a, a are the elevating handwheels or cranks B, B and the corresponding pedals B, B. The handwheels or cranks and the pedals are carried by brackets attached either to the side cheeks A, A or to the chamber A.

Referring more particularly to Figs. 3 and 4, which are assumed to show the elevating mechanism, the elevating hand wheel" or crank B is connected by bevel gearing for example, to a shaft b which is hereinafter referred to as the main elevating shaft, and

the pedals B are connected also through bevel gearing with a shaft 6' which is herebetween the hand wheel or crank B, the

pedals B and the elevating pinion C. By these means the handwheel or crank and the pedals can be operated independently or simultaneously to move the gun; by operating them simultaneously the elevating number can exert an increased amount of power upon the elevating mechanism so that large movements of the gun can be effected with ins carried by a sleeve B '96 v the minimum inconvenience to the elevating number; the final adual movement of the gun to bring the sight u on the tar et can then be made by means '0 .the handw eel or crank .with the elevating number in a more composed condition than would have been the case if he had been compelled to move the gun through large angles by the hand Wheel or crank alone.

It will be understood that similar mecha nism may be em loyedl for the training handwheel or cra and the training pedals, and also that any other form of mechanism can be used for the purpose of enabling the elevating or training handwheel or crank and the pedals to be operated independently to move the gun. v L

What we claim and deslre to-secure by 7. Letters Patent of the United States is 1 In agun mounting, the combination with the elevating gear, of a hand operated device: for actuating said gear and a foot operated device for actuating said gear, 531i devices being operable by the same gunner and the foot operated device being auxiliary to 'the hand operated device. l

2. In a gun mounting,- the combination with the training gear, of a'hand operated device for actuating said gear and a .footoperated device for actuating said gea'r, said devices being operable by the same gunner and the foot operated device being auxiliary to the hand operated device. j

3. In agun mounting, the combination with the elevating gear, of a hand operated device for actuating said gear, pedals also serving to actuate said gear, said device and "pedals being operated by the same gunner,

and means for enabling said device and the pedals to be operated either simultaneously or independently, said pedals being auxiliary to the hand-operated device.

4. In a gun mounting, the combination with the training gear, of a hand operated device for actuating said gear, pedals also serving toactuate said gear said device and pedals being operated by the same gunner, and'means for enabling said device and the pedals to be operated either simultaneouslly or independently, sa'id pedals-being auxi iary to the hand operated device.

5. In a gun mounting, the combination. wlth the elevating gear, of a hand operated. "devlce for actuat ng said gear, pedals also serving to actuate said gear, said device and pedals being operated by the same gunner and diflt'er'ential gear interposed between with the elevating gear, of ahand operated device for actuating said gear, a foot operated devlce for actuating said gear, said devices being operated by the same gunner and the foot operated" device being auxiliary .to the hand operated device, and a chamber and diiit'erential gear lnterposed between said tralning gear and the said device and movin with thegun in training for accommodatmg said footoperated device and the gunners legs.

8. In a gun mounting, the combination with the training gear, of a hand operated device for actuatlng said gear, a foot operated device for actuating said gear, said devices being operated by the same gunner and the foot operated device being auxiliary to the hand operated device, and a chamber moving with the gun in framing for accom-v modating said foot operated device, and the gunners legs.

In testimony whereof we afiix our signatures in the presence of two witnesses.
